FDR's program of price controls from 1939-43 is one example. To achieve that success they did have to do as Venezuela is attempting to do now, set up groups, at that time mostly volunteers, there were thousands of them, to keep track of compliance and to educate people who had questions about what prices they should pay, and for businesses, they should charge.
Compliance was good, there were some who tried to take advantage of the situation as always, but overall, people did abide by the rules.
Venezuela may be modeling their program on FDR's. The setting up of those 3,000 organizations eg, is similar to what he did.
I am certain that there were those who objected to the policies and we know from historical accounts, there were the usual predators.
But my point was that the reason such policies fail is generally because of non-compliance by those who see every human crisis as an opportunity for their own personal gain. Predators iow. FDR made it hard for them to operate.
And btw, the price controls implemented by FDR were far more extensive than just food. But he did it for the good of the country, as the Venezuelan Govt is trying to do.
There are other examples, but i'm not here to educate people about history, I don't have that much free time on my hands.
As for your claim, without any proof, that the Ven. Govt is after innocent housewives buying two doz eggs instead of one, that is preposterous. Unless Ven housewives are in possession of huge Warehouses where they are keeping their measly supplies of eggs. Please try to stick to facts.
